Title: Surface acoustic wave device and its manufacture
Inventor: WAKAMORI SATOSHI
IPC: H03H9/25
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To attain superior frequency characteristics and small-sized constitution by providing a seal layer which is fixed in a cap so that at least the main part of the electrode pattern of a surface acoustic wave chip is not covered with the seal layer and also has adhesiveness for sealing the joint part between the peripheral part and the opening end of the cap. SOLUTION: A SAW chip 3 is arranged on an insulating substrate with many electrodes SAWs 11a and 11b down. Neither the SAW 11a nor 11B is touched directly and the substrate 1 faces across a gap 19 so that the vibration of the SAWs 11a and 11b is not suppressed. A sealant 20 with high viscosity and adhesiveness is injected into the cap 4 by a specific amount to fill the gap between the chip 3 and cap 4. The sealant 20 has the high viscosity, so it does not penetrate up to the gap 19 between the substrate 1 and chip 3 and the main parts of the SAWs 11a and 11b are not covered with the sealant 20, so that the gap 19 is secured. A surface acoustic wave has no loss and frequency characteristics outside and inside the bank are improved.

Title: Manufacture of fiber reinforced plastic hollow body
Inventor: KAGEYAMA YASUSHI
IPC: B29C45/14
Filed: 1990-04-25
Abstract: PURPOSE:To produce a fiber reinforced plastic hollow body, which has high strength and rigidity and desired wall thickness, without increasing production cost by a method wherein the hollow body is produced by joining two split semi-fabricated products, which are fabricated at the same time. CONSTITUTION:An upper panel 23 and a lower panel 24 are formed through the closing of an upper and a lower slide cores 9 and 14 and a core 18 by bringing an upper and a lower press platens 12 and 17 close to each other under the condition that resin-impregnated glass fiber base material cut in proper lengths is fed between an upper mold 8 and the core 18 and between the core 18 and a lower mold 13. In this case, only the main body parts of both the panels excluding their peripheral edge parts are hardened under the condition that heated fixed molds 10, 10, 15 and 15 are brought out of contact with both the panels 23 and 24. After that, by opening the molds 8 and 13 through the separation of the upper and the lower press platens 12 and 17 from each other, both the panels 23 and 24 are left respectively on the slide core 9 side and on the slide core 14 side. After the core 18 is removed and the slide cores 9 and 14 are retreated to proper positions, closing is performed again, resulting in pressing and thermally hardening the peripheral edge parts of both panels 23 and 24 with the fixed molds 10, 10, 15 and 15.

Title: Transformer differential relay
Inventor: SUTANREI BURUUSU UIRUKINSON
IPC: G06F11/14
Filed: 1991-04-16
Abstract: PURPOSE: To discriminate the difference of a surge current easily from the difference of current due to internal failure by detecting the positive and negative parts of a current flowing through at least two windings of a transformer individually and tripping a relay when respective specified values area exceeded simultaneously. CONSTITUTION: Currents flowing through at least two windings, e.h. phases A, B, of a transformer are determined by CT 32, 34. Positive parts IA, IB and negative parts -IA, -IB of the current are detected and IA, -IB are then subjected to additional amplification 38. Current of phase C is determined from a CT 36 as -IA+IB and subjected to additional amplification 42. When a transformer to be protected has more than one winding, a signal related to the -IA+IB is generated additionally and subjected to additional amplification 44. Outputs from respective amplifiers 38, 42, 44 are subjected to additional amplification 46 to produce a vector sum operation VSO signal. Furthermore, outputs from the amplifiers 38, 42, 44 are converted 48, 50, 52 to absolute values which are then added 54 to produce a percentage suppression signal PR.  According to the arrangement, the difference of surge current can be discriminated easily from a fault current.

Title: Treatment of continuous casting slab
Inventor: IGARASHI KAZUHIRO
IPC: B21B1/02
Filed: 1984-05-31
Abstract: PURPOSE:To eliminate the need for a heating or holding cover for the purpose of sizing in the stage of sizing slabs to be sized such as taper-width slabs such are continuous casting slabs by a blooming mill by stacking the slabs to be sized on the inside of the non-sizing slabs feeding the slabs to the blooming mill. CONSTITUTION:Overwidth slabs such as taper-width slabs generated in the stage of an operation for changing the width of continuous casting slabs during continuous casting are sized by the blooming mill in order to be made coincident with the final product width. The slabs cut to a specified length right after continuous casting in this case are at a high temp. and therefore n-sheets of the slabs are stacked on a carriage (a) and 1 and (n) among these slabs are made non-sizing slabs and the slabs up to 2-(n-1) are made the slabs to be sized. The slabs 2-(n-1) maintain the high temp. as the heat thereof is held by the own heat and the heat retained in the upper and lower non-sizing slabs 1, (n). The sizing treatment is thus executed without the need for fresh heating of the slabs or the need for the holding cover.
